This invention aims to provide asimple but novel means for mixing coloring matter with oleomargarine or a similar substance,

novel means being provided whereby the ma- 5' terial, having been colored,'may be expelled in a strip of predetermined cross sectional contour.

It is wlthin the province of the disclosure I to improve generally and to enhance the utility of devices of that type to which the invention appertains.

v p the above and which will appear as other objects in view, the description pro ceeds, the invention residesin the combination and arrangement of parts and inthe de tails of construction hereinafter. described and claimed, it being understood that changes in the'precise embodiment. of the invention herein disclosed ,may

scope of what isclalmed, without departing from the spirit.

In the drawings Figure 1 shows device constructed 1n accordance of the invention.

1n longitudinal. section a invention, parts beingin elevation; Figure 2is a cross section on the line A-B of Figum-1, looking in the direction of the arrow marked 2; FigureB is a cross section on the line .A .-B of Figure 1 looking in'thedirection of the arrow marked The numeral 3. 1 designates a receptacle which may comprise a cylindrical body 2, the

same havmg a throughout its length, 0nd cap 4:. being ing or otherwise,

uniform internal diameter a ,first cap 3 anda secheld .detachably, by threadon the respective ends of the body 2. The cap 3 has an elongated hearing 5. The cap l may be of rectangular outline, the cap ing supplied. with posed about the opening has an openlng 6, which 4: bean external neck 7, disbeing threaded on the neck'i. The opening 6 is stopped by a closure block, shaped to to terminate cylinder cavity. the carrier 8 by struction being sure 9 may be opening 6, the cap or carrier canbe threaded 9, in the form of a fit closely in the opening and flush with the end wall of the The closure 9 is held on a pivot element 10, the consuch that although the cloheld against rotation in the 8,]nevertheless,

on the neck 7. The receptacleis held onthe'edge of the table, or on any other accessible support, through the instrumentality of a clamp 2 and to hold 11 carried by the body the receptacle the more'se be made within the with the v to said axis.

6, a carrier cap 8 curely on a support, the body 2 is provided with a transverse foot 12.

operating member is mounted for longitudinal movement in the receptacle 1 and may be in the form of a quick-thread screw 14 threaded into the bearing 5 of the first cap 3 and suppliedv at its outer end with a handle 15, a head 16, in the form of a disk, being secured to the inner end of the screw 14, the head being located within the receptacle 1 and having perforations 18.. The head fits the cylinder snugly so as to be guided by it and leave no substantial film of material adhering to the cylinder walls as it is moved back andforth and rotates within the cylinder. The device comprises, also, an imperforate disk-like follower 19 adapted to be placed in the receptacle 1 in advance of the head 16, the follower carrying a pivoted handle 20 whereby the follower maybe manipulated conveniently. ,When in place the follower abuts against the head so as to leave no substantial space therebetween.

The inner walls of the caps 3 and a, which form the end walls of the cylinder cavity, are preferably in planes cylinder axis, as shown, and the side walls of the head are also in planes at right angles It isessential that no substan tial space be left between thecap and the head when the latter is moved to either end of the cylinder.

Consequently, it is necessary that the inner surfacesof the end caps and the adjacent surfaces of-the head lie in parallel planes,

Assume that the closure 9 is; in place, as in Figure l, that the receptacle 1 contains coloring matter and materlal to be colored, that the cap 3 is in place, that the head 16 is re tracted, and that the follower 19 is omitted. Then, when the screw 14 is rotated by means of the handle 15, the screw will move longitudinally, causing the foraminous head 16 to reciprocate and rotate in the receptacle 1,

the material to becolored and the coloring matterbeingsqueezed back and forth through the perforations 18 of the head 16, until the coloring matter is distributed evenly through the material which is to be colored. Then, if the mixed material is to be ejected through the opening 6, the cap 3 is removed, and with it the head 16. .The follower 19 is mounted in lace-in the receptacle 1, and the cap ,3 is rep aced. The'device then appears as in Figure 1, The carrier 8 is detached,

at" right angles, to the the closure 9 being withdrawn from the opening 6. If, now, the screw 14, the head. 16 and the imperforate follower 19 be advanced, the colored material will be pressed out through the opening 6 in the form of a strip having a rectangular cross section, and the strip may be cut up into cubes of the common kind in which butter or oleomargarine is prepared for table use.

It will be understood that, as the head 16 moves longitudinal y within the cylinder, it also rotates therein; that the material is forced through the several perforations 18 and that it forms back of each perforation in a spiral-shaped, rod-like body. Since the perforations are in concentric rows, the material issuing through the outer rows is twisted about the material issuing through the inner rows, with the result that, when the head reaches the end of the cylinder, the material has all been forced through the perforations and lies behind the head in a ropelike mass. Upon the return of the head, this mass is again compressed and a similar rope- ].ike mass is formed on the opposite side of the head. As the head closely fits the sides of the cylinder and contacts closely with the caps when at the ends of its movements, all the material is subjected to the mixing action, with the result that the mixing of the material and the coloring matter is thorough and com plete. It will be noted further that, due to the elongated bearing for the screw, a powerful thrust upon the material is made possible, while the close fit of the head within the cylinder assures that the thrust will be directly in the cylinder axis.

Among other combinations, the device comprises a receptacle 1 having an outlet 6, a removable closure 9 for the outlet, an operat ing member 14 movable in the receptacle, a mixing element 16 and an expelling element 19, both movable responsive to the operating member, the expelling element being removable at the will of the operator.

During the mixing operation, some prefer to leave off the cap 8 and the closure 9, and let the following disk 19 abut against the cap 4:, as-indicated in dotted lines in Figure 1.
